The purpose of this study is to evaluate three foliar applied products and their ability to increase plant health and profitability.

In recent years, soybean foliar nutrition has been a hot topic. This year, we tested three different products at two different timings at the Iowa PFR site. None of the products tested resulted in a positive return on investment in 2017. Based on our data, it is unlikely that micronutrients were a limiting factor in our overall yield at this location. Further testing of these products in different growing environments will give us a better understanding of what conditions are likely to show a response.
